PRINTING-PRESS.

Specification of Letters Patent.

Patented June 14, 1910.

Application filed January 15, 1910. Serial No. 588,260.

T 0 all whom it may concern:

Be it known that I, THOMAS WINLAoK, a citizen of the United States,residing at Niles, count-y 0f Berrien, and State of Michigan, haveinvented certain new and useful Improvements in Printing-Presses, ofwhich the following is a specification.

My invention relates to improvements in that class of printing pressesemploying composition inking rolls. These rolls are made of acomposition having a low melting point so that in the summer time saidrolls are frequently melted and destroyed by the heat of the frictionincident to their use.

The object of my invention is to provide means on the press forpreventing this melting of the inking rolls, which shall be of simpleconstruction, eflicient in operation and readily attached or detachedfrom the press.

The invention consists in the combination and arrangement of partshereinafter described and claimed.

The invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification, and inwhich,

Figure 1 is a perspective view of a printing press embodying myinvention, Fig. 2, an enlarged sectional elevation showing the inkingrolls and cooling fan, and Fig. 3, an elevation of one of the bearingsfor supporting the cooling fan.

.The preferred form of construction comprises a flat fan 1 carried by ashaft 2 mounted in bearings 3 at either side of the press and soarranged as to position the fan 1 in close proximity to the inking rolls4 of the press. Each of the bearings 3 is supported upon a standard 5secured to the side of the frame of the press and comprising lowerbearing portions 6 and upper bearing portions 7 hinged thereto. At itsend opposite to its hinge the member 7 carries a swinging locking bolt 8adapted to take between lugs 9 on the member 6 to secure said member 7in position. Near one end shaft 2 carries a small spur gear 10 meshingwith the large driving gear 11 attached to the end of cylinder 12.

By the construction above set forth, it will be observed that a blast ofair will be forced across the inking rolls 5 keeping them cool and thatthe fan and its operating parts may be readily attached to or detachedfrom the press when desired.

WVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation or modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the exact detailsof construction set forth but desire to avail myself of such variationsand modifications as come within the scope of the appended claim.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

The combination with the inking rolls of a printing press having animpression cylinder provided with a driving gear at one end; standardsat either side of the press; hearings on said standards located inalinement above said inking rolls, each of said bearings comprising alower bearing member, an upper bearing member hinged to said lowerbearing member and a detachable locking connection between said bearingmembers; a shaft in said bearing; a gear on said shaft meshing with saidcylinder gear; and a fan on said shaft adapted to force a blast of airover said inking rolls, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

THOMAS INLACK.
